BACKGROUND Field

Aspects of the present disclosure relate generally to wirelesscommunication systems, and more particularly, to physical uplink controlchannel (PUCCH) repetition.

Background

Wireless communication networks are widely deployed to provide variouscommunication services such as voice, video, packet data, messaging,broadcast, and the like. These wireless networks may be multiple-accessnetworks capable of supporting multiple users by sharing the availablenetwork resources. Such networks, which are usually multiple accessnetworks, support communications for multiple users by sharing theavailable network resources. One example of such a network is theUniversal Terrestrial Radio Access Network (UTRAN). The UTRAN is theradio access network (RAN) defined as a part of the Universal MobileTelecommunications System (UMTS), a third generation (3G) mobile phonetechnology supported by the 3rd Generation Partnership Project (3GPP).Examples of multiple-access network formats include Code DivisionMultiple Access (CDMA) networks, Time Division Multiple Access (TDMA)networks, Frequency Division Multiple Access (FDMA) networks, OrthogonalFDMA (OFDMA) networks, and Single-Carrier FDMA (SC-FDMA) networks.

A wireless communication network may include a number of base stationsor node Bs that can support communication for a number of userequipments (UEs). A UE may communicate with a base station via downlinkand uplink. The downlink (or forward link) refers to the communicationlink from the base station to the UE, and the uplink (or reverse link)refers to the communication link from the UE to the base station.

A base station may transmit data and control information on the downlinkto a UE or may receive data and control information on the uplink fromthe UE. On the downlink, a transmission from the base station mayencounter interference due to transmissions from neighbor base stationsor from other wireless radio frequency (RF) transmitters. On the uplink,a transmission from the UE may encounter interference from uplinktransmissions of other UEs communicating with the neighbor base stationsor from other wireless RF transmitters. This interference may degradeperformance on both the downlink and uplink.

As the demand for mobile broadband access continues to increase, thepossibilities of interference and congested networks grows with more UEsaccessing the long-range wireless communication networks and moreshort-range wireless systems being deployed in communities. Research anddevelopment continue to advance wireless technologies not only to meetthe growing demand for mobile broadband access, but to advance andenhance the user experience with mobile communications.

Physical uplink control channel (PUCCH) repetition in different slotswas developed and implemented in Rel. 15 for PUCCH formats 1, 3, and 4.As implemented, the same PUCCH-SpatialRelationInfo is used in allrepetitions. Additionally, a resource control configuration for a givenPUCCH format provides the number of repetitions using a respectivenumber of slots (“nrofSlots”). Accordingly, the same PUCCH resource isused across all the repetitions—i.e., for each slot. However, theapproach implemented in Rel. 15 for PUCCH repetitions lacks flexibilityand adaptability to account for changing network conditions.

DETAILED DESCRIPTION

The detailed description set forth below, in connection with theappended drawings, is intended as a description of variousconfigurations and is not intended to limit the scope of the disclosure.Rather, the detailed description includes specific details for thepurpose of providing a thorough understanding of the inventive subjectmatter. It will be apparent to those skilled in the art that thesespecific details are not required in every case and that, in someinstances, well-known structures and components are shown in blockdiagram form for clarity of presentation.

This disclosure relates generally to providing or participating inauthorized shared access between two or more wireless communicationssystems, also referred to as wireless communications networks. Invarious embodiments, the techniques and apparatus may be used forwireless communication networks such as code division multiple access(CDMA) networks, time division multiple access (TDMA) networks,frequency division multiple access (FDMA) networks, orthogonal FDMA(OFDMA) networks, single-carrier FDMA (SC-FDMA) networks, LTE networks,GSM networks, 5th Generation (5G) or new radio (NR) networks, as well asother communications networks. As described herein, the terms “networks”and “systems” may be used interchangeably.

An OFDMA network may implement a radio technology such as evolved UTRA(E-UTRA), IEEE 802.11, IEEE 802.16, IEEE 802.20, flash-OFDM and thelike. UTRA, E-UTRA, and Global System for Mobile Communications (GSM)are part of universal mobile telecommunication system (UMTS). Inparticular, long term evolution (LTE) is a release of UMTS that usesE-UTRA. UTRA, E-UTRA, GSM, UMTS and LTE are described in documentsprovided from an organization named “3rd Generation Partnership Project”(3GPP), and cdma2000 is described in documents from an organizationnamed “3rd Generation Partnership Project 2” (3GPP2). These variousradio technologies and standards are known or are being developed. Forexample, the 3rd Generation Partnership Project (3GPP) is acollaboration between groups of telecommunications associations thataims to define a globally applicable third generation (3G) mobile phonespecification. 3GPP LTE is a 3GPP project which was aimed at improvingthe UMTS mobile phone standard. The 3GPP may define specifications forthe next generation of mobile networks, mobile systems, and mobiledevices. The present disclosure is concerned with the evolution ofwireless technologies from LTE, 4G, 5G, NR, and beyond with sharedaccess to wireless spectrum between networks using a collection of newand different radio access technologies or radio air interfaces.

In particular, 5G networks contemplate diverse deployments, diversespectrum, and diverse services and devices that may be implemented usingan OFDM-based unified, air interface. In order to achieve these goals,further enhancements to LTE and LTE-A are considered in addition todevelopment of the new radio technology for 5G NR networks. The 5G NRwill be capable of scaling to provide coverage (1) to a massive Internetof things (IoTs) with an ultra-high density (e.g., ˜1M nodes/km²),ultra-low complexity (e.g., ˜10s of bits/sec), ultra-low energy (e.g.,˜10+ years of battery life), and deep coverage with the capability toreach challenging locations; (2) including mission-critical control withstrong security to safeguard sensitive personal, financial, orclassified information, ultra-high reliability (e.g., ˜0.99.9999%reliability), ultra-low latency (e.g., ˜1 ms), and users with wideranges of mobility or lack thereof; and (3) with enhanced mobilebroadband including extreme high capacity (e.g., ˜10 Tbps/km²), extremedata rates (e.g., multi-Gbps rate, 100+ Mbps user experienced rates),and deep awareness with advanced discovery and optimizations.

The 5G NR may be implemented to use optimized OFDM-based waveforms withscalable numerology and transmission time interval (TTI); having acommon, flexible framework to efficiently multiplex services andfeatures with a dynamic, low-latency time division duplex(TDD)/frequency division duplex (FDD) design; and with advanced wirelesstechnologies, such as massive multiple input, multiple output (MIMO),robust millimeter wave (mmWave) transmissions, advanced channel coding,and device-centric mobility. Scalability of the numerology in 5G NR,with scaling of subcarrier spacing, may efficiently address operatingdiverse services across diverse spectrum and diverse deployments. Forexample, in various outdoor and macro coverage deployments of less than3 GHz FDD/TDD implementations, subcarrier spacing may occur with 15 kHz,for example over 1, 5, 10, 20 MHz, and the like bandwidth. For othervarious outdoor and small cell coverage deployments of TDD greater than3 GHz, subcarrier spacing may occur with 30 kHz over 80/100 MHzbandwidth. For other various indoor wideband implementations, using aTDD over the unlicensed portion of the 5 GHz band, the subcarrierspacing may occur with 60 kHz over a 160 MHz bandwidth. Finally, forvarious deployments transmitting with mmWave components at a TDD of 28GHz, subcarrier spacing may occur with 120 kHz over a 500 MHz bandwidth.

The scalable numerology of the 5G NR facilitates scalable TTI fordiverse latency and quality of service (QoS) requirements. For example,shorter TTI may be used for low latency and high reliability, whilelonger TTI may be used for higher spectral efficiency. The efficientmultiplexing of long and short TTIs to allow transmissions to start onsymbol boundaries. 5G NR also contemplates a self-contained integratedsubframe design with uplink/downlink scheduling information, data, andacknowledgement in the same subframe. The self-contained integratedsubframe supports communications in unlicensed or contention-basedshared spectrum, adaptive uplink/downlink that may be flexiblyconfigured on a per-cell basis to dynamically switch between uplink anddownlink to meet the current traffic needs.

Various other aspects and features of the disclosure are furtherdescribed below. It should be apparent that the teachings herein may beembodied in a wide variety of forms and that any specific structure,function, or both being disclosed herein is merely representative andnot limiting. Based on the teachings herein one of an ordinary level ofskill in the art should appreciate that an aspect disclosed herein maybe implemented independently of any other aspects and that two or moreof these aspects may be combined in various ways. For example, anapparatus may be implemented or a method may be practiced using anynumber of the aspects set forth herein. In addition, such an apparatusmay be implemented or such a method may be practiced using otherstructure, functionality, or structure and functionality in addition toor other than one or more of the aspects set forth herein. For example,a method may be implemented as part of a system, device, apparatus, oras instructions stored on a computer readable medium for execution on aprocessor or computer. Furthermore, an aspect may include at least oneelement of a claim.

FIG. 1 is a block diagram illustrating 5G network 100 including variousbase stations and UEs configured according to aspects of the presentdisclosure. The 5G network 100 includes a number of base stations 105and other network entities. A base station may be a station thatcommunicates with the UEs and may also be referred to as an evolved nodeB (eNB), a next generation eNB (gNB), an access point, and the like.Each base station 105 may provide communication coverage for aparticular geographic area. In 3GPP, the term “cell” can refer to thisparticular geographic coverage area of a base station or a base stationsubsystem serving the coverage area, depending on the context in whichthe term is used.

A base station may provide communication coverage for a macro cell or asmall cell, such as a pico cell or a femto cell, or other types of cell.A macro cell generally covers a relatively large geographic area (e.g.,several kilometers in radius) and may allow unrestricted access by UEswith service subscriptions with the network provider. A small cell, suchas a pico cell, would generally cover a relatively smaller geographicarea and may allow unrestricted access by UEs with service subscriptionswith the network provider. A small cell, such as a femto cell, wouldalso generally cover a relatively small geographic area (e.g., a home)and, in addition to unrestricted access, may also provide restrictedaccess by UEs having an association with the femto cell (e.g., UEs in aclosed subscriber group (CSG), UEs for users in the home, and the like).A base station for a macro cell may be referred to as a macro basestation. A base station for a small cell may be referred to as a smallcell base station, a pico base station, a femto base station or a homebase station. In the example shown in FIG. 1, the base stations 105 dand 105 e are regular macro base stations, while base stations 105 a-105c are macro base stations enabled with one of 3 dimension (3D), fulldimension (FD), or massive MIMO. Base stations 105 a-105 c takeadvantage of their higher dimension MIMO capabilities to exploit 3Dbeamforming in both elevation and azimuth beamforming to increasecoverage and capacity. Base station 105 f is a small cell base stationwhich may be a home node or portable access point. A base station maysupport one or multiple (e.g., two, three, four, and the like) cells.

The 5G network 100 may support synchronous or asynchronous operation.For synchronous operation, the base stations may have similar frametiming, and transmissions from different base stations may beapproximately aligned in time. For asynchronous operation, the basestations may have different frame timing, and transmissions fromdifferent base stations may not be aligned in time.

The UEs 115 are dispersed throughout the wireless network 100, and eachUE may be stationary or mobile. A UE may also be referred to as aterminal, a mobile station, a subscriber unit, a station, or the like. AUE may be a cellular phone, a personal digital assistant (PDA), awireless modem, a wireless communication device, a handheld device, atablet computer, a laptop computer, a cordless phone, a wireless localloop (WLL) station, or the like. In one aspect, a UE may be a devicethat includes a Universal Integrated Circuit Card (UICC). In anotheraspect, a UE may be a device that does not include a UICC. In someaspects, UEs that do not include UICCs may also be referred to asinternet of everything (IoE) or internet of things (IoT) devices. UEs115 a-115 d are examples of mobile smart phone-type devices accessing 5Gnetwork 100 A UE may also be a machine specifically configured forconnected communication, including machine type communication (MTC),enhanced MTC (eMTC), narrowband IoT (NB-IoT) and the like. UEs 115 e-115k are examples of various machines configured for communication thataccess 5G network 100. A UE may be able to communicate with any type ofthe base stations, whether macro base station, small cell, or the like.In FIG. 1, a lightning bolt (e.g., communication links) indicateswireless transmissions between a UE and a serving base station, which isa base station designated to serve the UE on the downlink or uplink, ordesired transmission between base stations, and backhaul transmissionsbetween base stations.

In operation at 5G network 100, base stations 105 a-105 c serve UEs 115a and 115 b using 3D beamforming and coordinated spatial techniques,such as coordinated multipoint (CoMP) or multi-connectivity. Macro basestation 105 d performs backhaul communications with base stations 105a-105 c, as well as small cell, base station 105 f. Macro base station105 d also transmits multicast services which are subscribed to andreceived by UEs 115 c and 115 d. Such multicast services may includemobile television or stream video, or may include other services forproviding community information, such as weather emergencies or alerts,such as Amber alerts or gray alerts.

5G network 100 also support mission critical communications withultra-reliable and redundant links for mission critical devices, such UE115 e, which is a drone. Redundant communication links with UE 115 einclude from macro base stations 105 d and 105 e, as well as small cellbase station 105 f. Other machine type devices, such as UE 115 f(thermometer), UE 115 g (smart meter), and UE 115 h (wearable device)may communicate through 5G network 100 either directly with basestations, such as small cell base station 105 f, and macro base station105 e, or in multi-hop configurations by communicating with another userdevice which relays its information to the network, such as UE 115 fcommunicating temperature measurement information to the smart meter, UE115 g, which is then reported to the network through small cell basestation 105 f. 5G network 100 may also provide additional networkefficiency through dynamic, low-latency TDD/FDD communications, such asin a vehicle-to-vehicle (V2V) mesh network between UEs 115 i-115 kcommunicating with macro base station 105 e.

FIG. 2 shows a block diagram of a design of a base station 105 and a UE115, which may be one of the base station and one of the UEs in FIG. 1.At the base station 105, a transmit processor 220 may receive data froma data source 212 and control information from a controller/processor240. The control information may be for the PBCH, PCFICH, PHICH, PDCCH,EPDCCH, MPDCCH etc. The data may be for the PDSCH, etc. The transmitprocessor 220 may process (e.g., encode and symbol map) the data andcontrol information to obtain data symbols and control symbols,respectively. The transmit processor 220 may also generate referencesymbols, e.g., for the PSS, SSS, and cell-specific reference signal. Atransmit (TX) multiple-input multiple-output (MIMO) processor 230 mayperform spatial processing (e.g., precoding) on the data symbols, thecontrol symbols, or the reference symbols, if applicable, and mayprovide output symbol streams to the modulators (MODs) 232 a through 232t. Each modulator 232 may process a respective output symbol stream(e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator232 may further process (e.g., convert to analog, amplify, filter, andupconvert) the output sample stream to obtain a downlink signal.Downlink signals from modulators 232 a through 232 t may be transmittedvia the antennas 234 a through 234 t, respectively.

At the UE 115, the antennas 252 a through 252 r may receive the downlinksignals from the base station 105 and may provide received signals tothe demodulators (DEMODs) 254 a through 254 r, respectively. Eachdemodulator 254 may condition (e.g., filter, amplify, downconvert, anddigitize) a respective received signal to obtain input samples. Eachdemodulator 254 may further process the input samples (e.g., for OFDM,etc.) to obtain received symbols. A MIMO detector 256 may obtainreceived symbols from all the demodulators 254 a through 254 r, performMIMO detection on the received symbols if applicable, and providedetected symbols. A receive processor 258 may process (e.g., demodulate,deinterleave, and decode) the detected symbols, provide decoded data forthe UE 115 to a data sink 260, and provide decoded control informationto a controller/processor 280.

On the uplink, at the UE 115, a transmit processor 264 may receive andprocess data (e.g., for the PUSCH) from a data source 262 and controlinformation (e.g., for the PUCCH) from the controller/processor 280. Thetransmit processor 264 may also generate reference symbols for areference signal. The symbols from the transmit processor 264 may beprecoded by a TX MIMO processor 266 if applicable, further processed bythe modulators 254 a through 254 r (e.g., for SC-FDM, etc.), andtransmitted to the base station 105. At the base station 105, the uplinksignals from the UE 115 may be received by the antennas 234, processedby the demodulators 232, detected by a MIMO detector 236 if applicable,and further processed by a receive processor 238 to obtain decoded dataand control information sent by the UE 115. The processor 238 mayprovide the decoded data to a data sink 239 and the decoded controlinformation to the controller/processor 240.

The controllers/processors 240 and 280 may direct the operation at thebase station 105 and the UE 115, respectively. The controller/processor240 or other processors and modules at the base station 105 may performor direct the execution of various processes for the techniquesdescribed herein. The controllers/processor 280 or other processors andmodules at the UE 115 may also perform or direct the execution of thefunctional blocks illustrated in FIGS. 8-19, or other processes for thetechniques described herein. The memories 242 and 282 may store data andprogram codes for the base station 105 and the UE 115, respectively. Ascheduler 244 may schedule UEs for data transmission on the downlink oruplink.

Wireless communications systems operated by different network operatingentities (e.g., network operators) may share spectrum. In someinstances, a network operating entity may be configured to use anentirety of a designated shared spectrum for at least a period of timebefore another network operating entity uses the entirety of thedesignated shared spectrum for a different period of time. Thus, inorder to allow network operating entities use of the full designatedshared spectrum, and in order to mitigate interfering communicationsbetween the different network operating entities, certain resources(e.g., time) may be partitioned and allocated to the different networkoperating entities for certain types of communication.

For example, a network operating entity may be allocated certain timeresources reserved for exclusive communication by the network operatingentity using the entirety of the shared spectrum. The network operatingentity may also be allocated other time resources where the entity isgiven priority over other network operating entities to communicateusing the shared spectrum. These time resources, prioritized for use bythe network operating entity, may be utilized by other network operatingentities on an opportunistic basis if the prioritized network operatingentity does not utilize the resources. Additional time resources may beallocated for any network operator to use on an opportunistic basis.

Access to the shared spectrum and the arbitration of time resourcesamong different network operating entities may be centrally controlledby a separate entity, autonomously determined by a predefinedarbitration scheme, or dynamically determined based on interactionsbetween wireless nodes of the network operators.

In some cases, UE 115 and base station 105 of the 5g network 100 (inFIG. 1) may operate in a shared radio frequency spectrum band, which mayinclude licensed or unlicensed (e.g., contention-based) frequencyspectrum. In an unlicensed frequency portion of the shared radiofrequency spectrum band, UEs 115 or base stations 105 may traditionallyperform a medium-sensing procedure to contend for access to thefrequency spectrum. For example, UE 115 or base station 105 may performa listen before talk (LBT) procedure such as a clear channel assessment(CCA) prior to communicating in order to determine whether the sharedchannel is available. A CCA may include an energy detection procedure todetermine whether there are any other active transmissions. For example,a device may infer that a change in a received signal strength indicator(RSSI) of a power meter indicates that a channel is occupied.Specifically, signal power that is concentrated in a certain bandwidthand exceeds a predetermined noise floor may indicate another wirelesstransmitter. A CCA also may include detection of specific sequences thatindicate use of the channel. For example, another device may transmit aspecific preamble prior to transmitting a data sequence. In some cases,an LBT procedure may include a wireless node adjusting its own backoffwindow based on the amount of energy detected on a channel or theacknowledge/negative-acknowledge (ACK/NACK) feedback for its owntransmitted packets as a proxy for collisions.

Use of a medium-sensing procedure to contend for access to an unlicensedshared spectrum may result in communication inefficiencies. This may beparticularly evident when multiple network operating entities (e.g.,network operators) are attempting to access a shared resource. In the 5Gnetwork 100, base stations 105 and UEs 115 may be operated by the sameor different network operating entities. In some examples, an individualbase station 105 or UE 115 may be operated by more than one networkoperating entity. In other examples, each base station 105 and UE 115may be operated by a single network operating entity. Requiring eachbase station 105 and UE 115 of different network operating entities tocontend for shared resources may result in increased signaling overheadand communication latency.

FIG. 3 illustrates an example of a wireless communications system 300that supports physical uplink control channel (PUCCH) repetition inaccordance with aspects of the present disclosure. In some examples,wireless communications system 300 may implement aspects of wirelesscommunication system 100. For example, wireless communications system300 may include UE 115 and base station 105. Although one UE and onebase station are illustrated, in other implementations, wirelesscommunications system 300 may include multiple UEs 115, multiple basestations 105, or both. For example, base station 105 (e.g., a networkentity) may include or correspond to a first base station (e.g., a firstnetwork entity), such as an eNB, and a second base station (e.g., asecond network entity), such as a gNB.

Base station 105 includes processor 302, memory 304, transmitter 310,receiver 312, and a radio resource control (RRC) configuration generator314. Processor 302 may be configured to execute instructions stores atmemory 304 to perform the operations described herein. In someimplementations, processor 302 includes or corresponds tocontroller/processor 240, and memory 304 includes or corresponds tomemory 242. Memory 304 may also be configured to store UE information320, beam information 322, one or more configuration settings 324,mapping information 326, and transmission configuration indicator (TCI)state information 328, as further described herein.

For example, the UE information 320 may indicate one or more UEs incommunication with base station 105. In some implementations, UEinformation 320 may include or indicate, for a UE, a PUCCH repetitionmode (e.g., scheme), RRC configuration information (e.g., 324), one ormore beams (e.g., 322), such as an activated beam for a PUCCH source,one or more TCI states, or a combination thereof.

Beam information 322 may identify one or more beams or a set of indicescorresponding to one or more beams. Configuration settings 324 mayinclude one or more settings for PUCCH repetition, such as a repetitionmode. To illustrate, configuration settings 324 may include one or morePUCCH resources. In some implementations, configuration settings 324 mayinclude a PUCCH resource set, and each set can include up to eight PUCCHresources, as an illustrative, non-limiting example. As an exception, afirst (e.g., initial) set may include up to thirty-two PUCCH resourceswhile other sets may only include up to eight PUCCH resources.Additionally, or alternatively, and one or more sets can be configured(e.g., via RRC configuration). For example, up to four sets may beconfigured (e.g., via RRC configuration), as an illustrative,non-limiting example. Which set to use may depend on the payload size ofuplink control information (UCI).

For a PUCCH resource, a set of RBs/symbols and a PUCCH format areindicated and configured per PUCCH resource (e.g., via RRCconfiguration). For example, PUCCH spatial relation information(“PUCCH-SpatialRelationInfo”) may be used indicate the beam to use for aPUCCH resource. Additionally, or alternatively, a set of indices(corresponding to a set of one or more beams—e.g., each index can pointto SSB/CSI-RS/SRS for reference signal) is configured by RRC for allPUCCH resources. For a given PUCCH resource, one index (e.g., beam) canbe activated by MAC-CE. In some implementations, power controlparameters are also included as part of PUCCH-SpatialRelationInfo.

In some implementations, memory 304 may include scheduling informationfor PUCCH included in the downlink control information (DCI) (DCI format1_0 or 1_1). The memory 304 may include or track aPDSCH-to-HARQ_feedback timing indicator field (a.k.a. K1 value). The K1value may include an index pointing a value of DL data to UL A/N in unitof slots from a configured set or a default set, such as {1, 2, 3, 4, 5,6, 7, 8}. The index may indicate or be used to determine which slot aHARQ-A for the scheduled PDSCH is to be to be transmitted on PUCCH.Additionally, configuration settings 324 may include a PUCCH resourceindicator (PRI). The PRI may include an index that is used to determinea PUCCH resource within a PUCCH resource set. In some implementations, aPRI in a last DCI is considered (among all the DCIs that have a value ofK1 indicating a same slot for PUCCH transmission).

Mapping information 326 information may include one or more datastructures for mapping a PRI field codepoint to one or more interpretedPRI values, as described further herein at least with reference to FIG.5. TCI state information 328 may a TCI code point which, in DCI, cancorrespond to one or two TCI states.

Transmitter 310 is configured to transmit data to one or more otherdevices, and receiver 312 is configured to receive data from one or moreother devices. For example, transmitter 310 may transmit data, andreceiver 312 may receive data, via a network, such as a wired network, awireless network, or a combination thereof. For example, base station105 may be configured to transmit or receive data via a directdevice-to-device connection, a local area network (LAN), a wide areanetwork (WAN), a modem-to-modem connection, the Internet, intranet,extranet, cable transmission system, cellular communication network, anycombination of the above, or any other communications network now knownor later developed within which permits two or more electronic devicesto communicate. In some implementations, transmitter 310 and receiver312 may be replaced with a transceiver. Additionally, or alternatively,transmitter 310, receiver, 312, or both may include or correspond to oneor more components of base station 105 described with reference to FIG.2.

RRC configuration generator 314 is configured to generate the one ormore RRC configuration settings. For example, RRC configurationgenerator 314 may generate one or more RRC configuration settings basedon UE information 320, beam information 322, configuration setting 324,mapping information 326, TCI state information 328, or a combinationthereof.

UE 115 includes processor 330, memory 332, transmitter 334, receiver336, a settings identifier 337, a resource selector 338, and a beamgenerator 339. Processor 330 may be configured to execute instructionsstored at memory 332 to perform the operations described herein. In someimplementations, processor 330 includes or corresponds tocontroller/processor 280, and memory 332 includes or corresponds tomemory 282. Memory 332 may also be configured to store one or morerepetition settings 340 and mapping information 326. The one or morerepetition settings 340 may be used by UE 115 to perform PUCCHrepetition one or more slot position, such as one or more slots, one ormore sub-slots, or a combination thereof. In some implementations, therepetition settings 340 may include or indicate one or more repetitionmodes.

Transmitter 334 is configured to transmit data to one or more otherdevices, and receiver 336 is configured to receive data from one or moreother devices. For example, transmitter 334 may transmit data, andreceiver 336 may receive data, via a network, such as a wired network, awireless network, or a combination thereof. For example, UE 115 may beconfigured to transmit or receive data via a direct device-to-deviceconnection, a LAN, a WAN, a modem-to-modem connection, the Internet,intranet, extranet, cable transmission system, cellular communicationnetwork, any combination of the above, or any other communicationsnetwork now known or later developed within which permits two or moreelectronic devices to communicate. In some implementations, transmitter334 and receiver 336 may be replaced with a transceiver. Additionally,or alternatively, transmitter 334, receiver, 336, or both may include orcorrespond to one or more components of UE 115 described with referenceto FIG. 2.

Setting(s) identifier 337 may receive one or more messages from basestation 105 and determine the one or more repetition settings 340, asdescribed herein. Resource selector 338 is configure to select one ormore PUCCH resources based on the one or more repetition settings 340.Beam generator 339 is configured to generate or use one or more beamsbased on the one or more repetition settings.

During operation of wireless communications system 300, base station 105may send a repetition indicator 360 to UE 115. Repetition indicator 360may indicate whether or not UE 115 is to perform PUCCH repetition,whether UE 115 is to perform a single repetition per slot position ormultiple repetitions for a slot position, a PUCCH repetition mode (e.g.,a PUCCH repetition scheme), or a combination thereof. In someimplementations, the repetition indicator 360 may indicate a repetitionmode of the UE 115.

Base station 105 may send a first message 361 to UE 115. First message361 may include or indicate UE information 320, beam information 322,configuration settings 324, TCI state information 328, or a combinationthereof. In some implementations, first message 361 may include orcorrespond to repetition indicator 360. First message 361 may include aRRC (e.g., one or more RRCs), a DCI, or a MAC-CE, as illustrative,non-limiting examples. In some implementations, first message 361includes one or more RCCs generated by RRC configuration generator 314.For example, RRC configuration generator 314 may generate a first RRCfor PUCCH—SpatialRelationInfo that indicates a set of indices for one ormore resources (e.g., one or more PUCCH resources). As another example,RRC configuration generator 314 may generate a second RRC forPUCCH-FormatConfig that indicates a number of slots (e.g., a value of a“nrofSlots” field). As another example, RRC configuration generator 314may generate a third RRC for PUCCH-Config (in Rel. 15) that indicates“spatialRelationInfoToAddModList” for all PUCCH resources. It is notedthat the second RRC (for PUCCH-FormatConfig (together with “nrofSlots”))may be different from the third RRC (for PUCCH-Config (in Rel. 15)) thatindicates “spatialRelationInfoToAddModList” for all PUCCH resources.

UE 115 receives repetition indicator 360, first message 361, or both,and settings identifier 337 processes the repetition indicator 360,first message 361, or both to determine repetition settings 340 (e.g.,PUCCH repetition settings). For example, settings identifier 337 mayprocess the repetition indicator 360, first message 361, or both,according to a repetition mode (e.g., a repetition scheme), such as aselected mode of multiple repetition modes. In some implementations, themode may be indicated by or selected based on repetition indicator 360.After repetition settings 340 are determined, UE 115 may performrepetition—e.g., transmit one or more PUCCH repetitions—based on therepetition settings 340. For example, resource selector 338 may select,based on repetition settings 340, one or more resources, such as one ormore PUCCH resources. Additionally, or alternatively, beam generator 339may select, based on repetition settings 340, one or more beams. Toillustrate, resource selector 338 may select a first resource (e.g., afirst PUCCH resource) for a first repetition 362, and beam generator 339may select a first beam for the first resource. As another example,resource selector 338 may select a second resource (e.g., a second PUCCHresource) for a second repetition 363, and beam generator 339 may selecta second beam (different from the first beam) for the second resource.

UE 115 transmits the first repetition 362, the second repetition 363, orboth, based on the repetition settings 340. To illustrate, UE 115 maytransmit first repetition 362 and second repetition during one or moreslot positions. The one or more slot positions may include or correspondto one or more slots, one or more sub-slots, or a combination thereof.As an example, first repetition 362 (for a first resource) istransmitted using a first beam of multiple beams during a first slotposition and second repetition (for a second resource) is transmittingusing a second beam of multiple beams during a second slot positions. Asanother example, first repetition 362 (for a first resource) istransmitted using a first beam of multiple beams during a first slotposition and second repetition (for a second resource) is transmittedusing a second beam of multiple beams during the first slot positions.

Base station 105 may receive first repetition 362, second repetition363, or both. Base station 105 may process first repetition 362, secondrepetition 363, or both, based at least on configuration settings 325.

In some implementations, UE 115 is configured with PUCCH repetitionthrough nrofSlots for a PUCCH format, and a PUCCH resource is used. Insuch implementations, UE 115 may not use the activatedPUCCH-SpatialRelationInfo for that PUCCH resource.

To illustrate, according to a first mode of operation (e.g., a firstscheme or a first option), UE 115 (e.g., 337) identifies a set ofindices configured by RRC for PUCCH-SpatialRelationInfo to be used(configured in IE PUCCH-Config for all the PUCCH resources in a BWP).During a first slot position, UE 115 uses a first beam (e.g., a lowestID: PUCCH-SpatialRelationInfold) to transmit first repetition 362;during a second slot position, UE uses a second beam (e.g., a next ID)to transmit second repetition 363; and so on. In some implementations,UE 115 selects between the first option and Rel. 15 behavior in whicheach repetition is sent using the same beam.

In some implementations of the first option, the first repetition 362(e.g., an initial transmitted repetition), may use the activatedPUCCH-SpatialRelationInfo for the resource (e.g., the PUCCH resource)that is used. The activated PUCCH-SpatialRelationInfo for the resourcemay be indicated in a MAC-CE. For one or more remaining repetitions(e.g., repetition(s) following the initial transmitted repetition), theset of indices configured by RRC for PUCCH-SpatialRelationInfo may beused.

Referring to FIG. 4, an example of the first option is shown andgenerally designated 400. Example 400 shows multiple slot positions,such as a first slot position 430 (e.g., Slot Position_0), a second slotposition 431 (e.g., Slot Position_1), a third slot position 432 (e.g.,Slot Position_2), and a fourth slot position 433 (e.g., SlotPosition_3). Although four slot positions are shown, this is not to beconsidered limiting and fewer than or more than four slot positions maybe present. A slot position may include a slot (e.g., an entirety of aslot) or a sub-slot. As an example of sub-slots, each of the first slotposition 430 and second slot position 431 may be sub-slots of the sameslot.

As shown in FIG. 4, a number of slot positions is equal to four. Forexample, in some implementations, nrofSlots (or “nrofSubslots”) is equalto four. With reference to example 400, in PUCCH-Config,“spatialRelationInfoToAddModList” contains three beams (IDs=0, 1, 2),but for pucch-ResourceId=x, beam_2 (i.e. PUCCH-SpatialRelationInfold=2)is activated through MAC-CE. Stated in another manner, three beams areavailable for all resources (e.g., PUCCH resources) and, for a resourcex, beam_2 is activated based on a MAC-CE. As shown in FIG. 4, the threebeam include a first beam 440 (e.g., beam_0), a second beam 441 (e.g.,beam_1), and a third beam 442 (e.g., beam_2). In FIG. 4, repetition inthe same resource (e.g., the same PUCCH resource)—i.e., resource x—isshown. According to the first mode, first slot position 430 uses thirdbeam 442 (e.g., beam_2) for repetition because third beam 442 (e.g.,beam_2) is the activated beam for resource x based on the MAC-CE. Afterthe first slot position 430, the set of three beams are used (e.g.,cycled through) for the remaining slot positions. To illustrate, forrepetition of resource x, first beam 440 (e.g., beam_0) is used forsecond slot position 431; second beam 441 (e.g., beam_1) is used forthird slot position 431; and third beam 442 (e.g., beam_2) is used forfourth slot position 443.

As shown in FIG. 4, for the remaining repetitions (after the initialrepetition), the beam (e.g., third beam 442 (e.g., beam_2)— theactivated beam) for the initial slot position is used again in the setof beams (440, 441, 442). In other implementations, the beam (e.g.,third beam 442 (e.g., beam_2)— the activated beam) for the initial slotposition may not be used again for the remaining repetitions (after theinitial repetition). In such an implementation, first beam 440 (e.g.,beam_0) is used for second slot position 431; second beam 441 (e.g.,beam_1) is used for third slot position 432; and first beam 440 (e.g.,beam_0) is used for fourth slot position 443. It is noted that if anumber of beams in PUCCH-SpatialRelationInfold is less than a number ofslot positions (e.g., “nrofSlots” or “nrofsubSlots”), after goingthrough the set, the beams available for use are cycled through one ormore times, as needed, until the number of slot positions is completed.

According to a second mode of operation (e.g., a second scheme or asecond option), UE 115 (e.g., 337) identifies a set of one or more beams(e.g., a set of PUCCH-SpatialRelationInfold for repetition beams) basedon or using a second RRC for PUCCH-FormatConfig. For example, in thesecond mode, a number of slot positions and a set of beams forrepetition may be defined by PUCCH-FormatConfig for each of one or moreformats. In some implementations, the set of beams can have a samenumber of beams as number of slot positions— i.e., a one-to-onecorrespondence between beams and slot positions. It is noted that if anumber of beams in PUCCH-SpatialRelationInfold is less than a number ofslot positions (e.g., “nrofSlots” or “nrofsubSlots”), after goingthrough the set, the beams available for use are cycled through one ormore times, as needed, until the number of slot positions is completed.In some implementations of the second mode, if the set of beams includesa single beam, the resource (e.g., the PUCCH resource) may switch tooperation according to Rel. 15 in which, for the resource, the same beamis used for repetition for each slot position.

It is noted that each of the first mode and the second mode may be usedfor slots (inter-slot repetition) and subslots (intra-slot repetition).For example, a set of beams may be cycled through on a per slot basis oron a per subslot basis. As another example, when a set of slot positionsincludes two or more slots each with multiple subslots, the set of beamsmay be cycled through per subslot. As another example, when a set ofslot positions includes two or more slots each with multiple subslots,the set of beams may be cycled through per slot, where a beam is usedfor multiple subslots for its correspond slot.

In some implementations, UE 115 may transmit, for a PUCCH resource, afirst PUCCH repetition (e.g., 362) for a first slot position and asecond PUCCH repetition (e.g., 363) for a second slot position. Forexample, the first PUCCH repetition may be transmitted using a secondbeam of multiple beams for the first slot position of the multiple slotpositions. The multiple slot positions may include multiple slots ormultiple sub-slots of a slot. In some implementations, such as when UE115 is configured according to the first mode, UE 115 receives an RRCconfiguration (e.g., 361) including a PUCCH resource. The UE 115 mayalso identify a set of indices for one or more PUCCH resources. Eachindex of the set of indices corresponding to a different beam ofmultiple beams. For example, UE 115 (e.g., 337) identifies a set ofindices configured by RRC for PUCCH-SpatialRelationInfo to be used(configured in IE PUCCH-Config for all the PUCCH resources in a BWP).Alternatively, in other implementations, such as when UE 115 isconfigured according to the second mode, UE 115 may identify a set ofindices for one PUCCH resource (e.g., a single resource), where eachindex of the set of indices corresponding to a different beam ofmultiple beams. For example, UE 115 may identify the set of indicesdefined by PUCCH-FormatConfig for each of one or more formats.

According to a third mode of operation (e.g., a third scheme or a thirdoption), UE 115 may identify one or more resources (e.g., PUCCHresources) based on PRI field codepoint in a DCI (e.g., 361). Forexample, the PRI field codepoint may indicate (e.g., point to) one PRIvalue or two PRI values. A PRI value may indicate a PUCCH resourcewithin a PUCCH resource set. The PRI field codepoint may be mapped toone or more “interpreted” PRI values using mapping information 326. Themapping between PRI field codepoint in the DCI and the one or moreinterpreted PRI values can be configured based on or responsive torepetition indicator 360 or based on first message 361, such asresponsive to an RRC configuration or a MAC-CE. When multiple PRI valuesare interpreted, multiple resources (e.g., PUCCH resources) may beidentified for repetition during a slot position. For example, UE 115may use a first PUCCH resource of the multiple PUCCH resources totransmit a first PUCCH repetition (e.g., 362) of the multiple PUCCHrepetitions within a slot position and use a second PUCCH resource ofthe multiple PUCCH resources to transmit, a second PUCCH repetition(e.g., 363) of the multiple PUCCH repetitions within the same slotposition (e.g., slot or subslot).

Referring to FIG. 5, an example of a data structure for mapping a PRIfield codepoint 502 to one or more interpreted PRI values 520 is shownand designated 500. Each PRI field codepoint is listed as an integerwith a corresponding binary representation in a parenthetical. As shown,for the case of one interpreted PRI value or two interpreted PRI values,the first PRI value is the same as the codepoint in the DCI.Accordingly, in such an implementation, only the second interpreted PRIis configured through RRC or activated through MAC-CE. Additionally, itis noted that the second interpreted PRI for some of the codepoints canbe “empty”, i.e., that codepoint only indicates one PRI value. Whenthere are two interpreted PRI values, the corresponding PUCCH resourcescan have different MAC-CE activated PUCCH-SpatialRelationInfo's. Forexample, the first interpreted value corresponds to a first PUCCHresource using a first beam and the second interpreted value correspondsto a second PUCCH resource using a second beam. In otherimplementations, the first PRI value is different from the codepoint inthe DCI, and the first interpreted value is configured through RRC oractivated through MAC-CE and the second interpreted value is configuredthrough RRC or activated through MAC-CE. Although data structure 500 hasbeen described as mapping a PRI field codepoint to one or twointerpreted PRI values, in other implementations, the data structure 500may be configured to map the PRI field codepoint to more than twointerpreted PRI values.

According to a fourth mode of operation (e.g., a fourth scheme or afourth option), UE 115 also uses PRI field codepoints for determiningrepetition (e.g., PUCCH repetition). In some implementations, the fourthmode and the third mode are part of the same mode of operation. Duringthe fourth mode, the UE 115 receives from a network (e.g., base station105) a DCI scheduling PDSCH and a PRI field can be used indicate whetherto use two PUCCH resources to repeat the PUCCH content (HARQ-Ackcodebook along with other UCIs in the case of UCI multiplexing). Forexample, the DCI (e.g., 361) may include a Downlink (DL) DCI schedulinga Physical Downlink Shared Channel (PDSCH), and the PUCCH repetitionincludes a Hybrid Automatic Repeat Request (HARQ)-ACK codebook.

Referring to FIG. 6, an example of the fourth mode is shown anddesignated 600. As shown, the example includes slot positions 430-433.During each of the slot positions 430-432, a DCI and data arecommunicated. For example, during first slot position 430, a first DCI610 and data 616 are communication; during second slot position 431, asecond DCI 620 and second data 626; and during third slot position 432,third DCI 630 and third data is communicated. Each DCI may have acorrespond K1 value and may indicate one or more PRI values 624. Forexample, first DCI 610 includes a first K1 value 612 (e.g., K1=3) andindicates a first set of PRI values 614 (e.g., PRI: a, b); second DCI620 includes a second K1 value 622 (e.g., K1=2) and indicates a secondset of PRI values 624 (e.g., PRI: a, c); and third DCI 630 includes athird K1 value 632 (e.g., K1=1) and indicates a third set of PRI values634. In some implementations, UE 155 receives each of DCIs 610, 620,630. During fourth slot position 433, UE 115 transmits PUCCH resource640 and PUCCH resource 650, as described herein. In someimplementations, one or more of the DCIs 610, 620, 630 indicate morethan two PRI values.

During the fourth mode, UE 115 receives the DCIs 610, 620, 630 andidentifies a set of DCIs in which each DCI has the same HARQ feedbacktiming indicator field (e.g., K1 value) indicating the same slotposition for PUCCH transmission of HARQ-ACK feedback. As shown in FIG.6, each of the DCIs 610, 620, 630 indicates fourth slot position 433 forPUCCH transmission of HARQ-ACK feedback.

In a first implementation of the fourth mode, UE 115 identifies a lastdetected DCI (e.g., 630) of the set of DCIs 610, 620, 630. UE 115determines whether to perform PUCCH repetition if the corresponding PRIfield codepoint (e.g., 634) of the last detected DCI (e.g., 630)indicates multiple PRI values. As shown, third DCI 630 indicates PRIvalue 634 as PRI: d—a single PRI. Since PRI value 634 indicates a singlePRI value, UE 315 would use PUCCH resource 640 (e.g., PUCCH resource dcorresponding to PRI value d) to send HARQ-ACK feedback during fourthslot position 433. In such an implementation, UE 115 would not use PUCCHresource 650 (e.g., PUCCH resource c). Alternatively, if third DCI 630indicated PRI values d and c, UE 115 would perform repetition duringfourth slot position 433 and would use each of PUCCH resource 640 (e.g.,PUCCH resource d corresponding to PRI value d) and PUCCH resource 650(e.g., PUCCH resource c corresponding to PRI value c) to send HARQ-ACKfeedback during fourth slot position 433.

In a second implementation of the fourth mode, UE 115 identifies a lastdetected DCI (e.g., 630) of the set of DCIs 610, 620, 630. UE 115determines whether to perform PUCCH repetition if at least one DCI ofthe set of DCI 610, 620, 630 has a corresponding PRI field codepointthat indicates multiple PRI values. As shown, both first DCI 610 andsecond DCI indicate multiple PRI values, so UE 115 determines to performrepetition. If the last detected DCI (e.g., 630) indicated multiple PRIvalues, UE 115 would use the PRI values indicated by third DCI 630.Alternatively, if the last detected DCI (e.g., 630) indicates a singlePRI value as shown, UE 115 perform repetition using a first PUCCHresource 640 corresponding to the single PRI value (e.g., PUCCH resourced) and using a second PUCCH resource 650 (e.g., resource c)corresponding to a most recently received DCI (e.g., 620) of the atleast one received DCI (e.g., 610, 620) that includes the value of thePRI field codepoint corresponding to the multiple PRI values. It isnoted that if second DCI 620 indicated a single PRI value, the mostrecently received DCI of the at least one received DCI (e.g., 610) thatincludes the value of the PRI field codepoint corresponding to themultiple PRI values is the first DCI 610 and, therefore, the UE 115would use PUCCH resource b as the second PUCCH resource 650.

In some implementations, the fourth mode may be used based on adetermination that a TCI filed in at least one DCI 610, 620, 630 pointsto two TCI states (PDSCH multi-TRP schemes SDM/FDM/TDM). In a particularimplementation, the fourth mode may be used based on a determinationthat a TCI in each of the DCIs 610, 620, 630 (having the same HARQfeedback timing indicator field (e.g., K1 value) indicating the sameslot position for PUCCH transmission of HARQ-ACK feedback) points to twoTCI states. If at least one DCI does not have a TCI field that points totwo TCI states, or alternatively, less than all of the DCIs a TCI thatpoints to two TCI states, UE 115 may operate according to Rel. 15behavior for the PRI value. Additionally, or alternatively, it is noted,that the fourth mode may be used with the third mode and a mapping datastructure, such as data structure 500. Accordingly, the fourth mode mayoperate based on interpreted PRI values indicated by DCIs 610, 620 630.

In a third implementation of the fourth mode, UE 115 identifies a PRIvalue, such as an interpreted PRI value. UE selects a first interpretedPRI value as the PRI codepoint value and determines the first PUCCHresource (e.g., 640) for repetition based on the first interpreted PRIvalue. The UE determines whether to use an additional (e.g., second)PUCCH resource based on one or more rules—e.g., one or more conditions.For example, UE may select the second PUCCH resource from among all theother PUCCH resources within a PUCCH resource set that: do not overlapwith the first PUCCH resource; start after the first PUCCH resource; hasa different MAC-CE activated PUCCH-SpatialRelationInfo than the firstPUCCH resource; the corresponding PUCCH-SpatialRelationInfo has the samequasi co-located (QCL) source as the second TCI state; or a combinationthereof. It is noted that the condition of the correspondingPUCCH-SpatialRelationInfo has the same QCL source as the second TCIstate may only be applicable in the case that the TCI field in the DCIpoints to two TCI states. The fourth mode of operation or any of theimplementations of the fourth mode described herein, can be RRCconfiguration.

Referring to FIG. 7, an example of the third implementation of thefourth mode is shown and designated 700. As shown, a DCI 710 (e.g., 361)includes two TCI states— TCI state i and TCI state j—and corresponds toPDSCH 720 and PDSCH 730. A PRI value codepoint (a) of DCI 710 isinterpreted as PRI values a and b. UE 115 selects first interpreted PRIvalue for the first PUCCH resource 740 For the second PUCCH resource750, UE 115 determines that the TCI state j and PUCCHSpatialRelationInfo for PUCCH resource b have the same QCL source. Basedon those conditions, UE 115 selects the second PUCCH resource 750 basedon PRI value b.

Thus, FIG. 3 describes PUCCH repetition. For example, a configurationmay transmit multiple repetitions (e.g., 362, 363) using differentresource or different beams. The multiple repetitions (e.g., 362, 363)may be transmitted during the same slot position or during differentslot positions. Additionally, UE 115 may be configured to perform PUCCHrepetition based on one or more modes. Each of the one or more modesprovides greater flexibility for UE 115 to perform PUCCH repetition notrealized by conventional systems. Accordingly, PUCCH repetitions aremove likely to be received during dynamically changing networkconditions as compared to conventional systems.

FIGS. 8-12 are block diagrams illustrating example blocks executed by aUE configured according to an aspect of the present disclosure. Theexample blocks will also be described with respect to UE 115 asillustrated in FIG. 8. FIG. 20 is a block diagram illustrating UE 115configured according to one aspect of the present disclosure. UE 115includes the structure, hardware, and components as illustrated for UE115 of FIG. 2 or 3. For example, UE 115 includes controller/processor280, which operates to execute logic or computer instructions stored inmemory 282, as well as controlling the components of UE 115 that providethe features and functionality of UE 115. UE 115, under control ofcontroller/processor 280, transmits and receives signals via wirelessradios 2001 a-r and antennas 252 a-r. Wireless radios 2001 a-r includesvarious components and hardware, as illustrated in FIG. 2 for UE 115,including modulator/demodulators 254 a-r, MIMO detector 256, receiveprocessor 258, transmit processor 264, and TX MIMO processor 266. Asshown, memory 282 may include repetition setting(s) 2002, mappinginformation 2003, setting identifier logic 2004, resource selector logic2005, and beam generator logic 2006. Repetition setting(s) 2002 andmapping information 2003 may include or correspond to repetitionsetting(s) 340 and mapping information 326, respectively. Settingidentifier logic 2004 may include or correspond to setting(s) identifier337. Resource selector logic 2005 may include or correspond to resourceselector 338. Beam generator logic 2006 may include or correspond tobeam generator 339. In some aspects, setting identifier logic 2004,resource selector logic 2005, beam generator logic 2006, or acombination thereof, may include or correspond to processor(s) 280. UE115 may receive signals from or transmit signal to a base station, suchas base station 105 of FIG. 3 or base station 105 as illustrated in FIG.21.

Referring to FIG. 8, at block 800, the UE receives an RRC configurationincluding a PUCCH resource. To illustrate, the UE may receive the RRCvia wireless radios 2001 a-r and antennas 252 a-r. The RRC configurationmay include or correspond to first message 361.

At block 801, the UE determines a set of indices for one or more PUCCHresources. Each index of the set of indices may correspond to adifferent beam of multiple beams. The multiple beams may include a firstbeam and a second beam. To illustrate, the UE may determine the set ofindices using setting identifier logic 2004. The set of indices mayinclude or correspond to repetition setting(s) 340.

At block 802, the UE transmits, for the PUCCH resource: a first PUCCHrepetition of multiple PUCCH repetitions using the first beam for afirst slot position of multiple slot positions; and a second PUCCHrepetition of the multiple PUCCH repetitions using the second beam for asecond slot position of the multiple slot positions. To illustrate, theUE may transmit the first PUCCH repetition and the second PUCCHrepetition via wireless radios 2001 a-r and antennas 252 a-r. The firstrepetition and the second repetition may include or correspond to firstrepetition 362 and second repetition 363, respectively. In someimplementations, the PUCCH resource may be selected by resource selectorlogic 2005. Additionally, or alternatively, the first beam and thesecond beam may be generated using beam generator logic 2006. In someimplementations, the first beam corresponds to a first index of the setof indices, the second beam corresponds to a second index of the set ofindices, or both. In some implementations, the multiple slot positionsinclude multiple slots or multiple sub-slots of a slot.

In some implementation, the PUCCH resource configuration indicates a setof resource blocks (RBs), a set of symbols, a PUCCH format, or acombination thereof. In some such implementations, the PUCCH formatindicates to perform PUCCH repetition based on a value of a number ofslots field, such as a “nrofSlots” field of the RRC configuration.Additionally, or alternatively, a block may include the UE determining,based on the RRC configuration, whether to perform PUCCH repetitionusing the same beam for the multiple slot positions or using themultiple beams for the multiple slot positions.

In some implementations, a block may include the UE receiving a MediumAccess Control (MAC)-Control Element (CE) for the PUCCH resource, anddetermining, based on the MAC-CE, an activated beam for the PUCCHresource. To illustrate, the activated beam may be determined usingsetting identifier logic 2004.

In some implementations, transmitting PUCCH repetitions includes: usingthe activated beam for a first slot position (e.g., an initial slotposition) of the multiple slot positions; and using the multiple beamsfor slot positions of the multiple slot positions occurring subsequentto the first slot position. In some such implementations, the activatedbeam is included as one of the multiple beams used for the slotpositions of the multiple slot positions occurring subsequent to thefirst slot position. Alternatively, the activated beam is omitted as oneof the multiple beams used for the slot positions of the multiple slotpositions occurring subsequent to the first slot position. Toillustrate, the activated beam may be included in or omitted from themultiple beams based on repetition setting(s) 2002.

In some implementations, a number of the multiple beams is equal to anumber of slot positions of the multiple slot positions—e.g., there is aone-to-one correspondence between the multiple beams and the number ofslot positions. If a number of the multiple beams is less than a numberof slot positions of the multiple slot positions, transmitting PUCCHrepetitions includes: cycling through the multiple beams for a first setof slot positions of the multiple slot positions, the first set of slotpositions including a number of slot positions equal to the number ofthe multiple beams; and using one or more beams of the multiple beamsfor a second set of slot positions of the multiple slot positions.

Referring to FIG. 9, at block 900, the UE receives a first RRCconfiguration including a PUCCH resource. To illustrate, the UE mayreceive the first RRC via wireless radios 2001 a-r and antennas 252 a-r.The first RRC configuration may include or correspond to first message361.

At block 901, the UE receives a second RRC configuration including aPUCCH format. To illustrate, the UE may receive the second RRC viawireless radios 2001 a-r and antennas 252 a-r. The first RRCconfiguration may include or correspond to first message 361. In someimplementations, the first and second RRC are included in the samemessage. In other implementations, the first RRC and the second RRC areincluded in different messages.

In some implementations, the first RRC configuration may include orcorrespond to a PUCCH-Config (e.g., “spatialRelationInfoToAddModList”)for all PUCCH resources. Additionally, or alternatively, the second RRCconfiguration may include or correspond to a PUCCH-FormatConfig, andoptionally, also with a number of slots (e.g., “nrofSlots”) field.Accordingly, an RRC parameter for multiple beams (e.g., for purposes ofrepetition) may be defined based on the first RRC, the second RRC, orboth the first and second RRCs. In some implementations, the second RRCincludes multiple PUCCH formats and, for each PUCCH format included inthe second RRC configuration, the second RRC configuration indicates acorresponding set of one or more beams.

At block 902, the UE determines, based on the PUCCH resource and thePUCCH format, multiple beams. The multiple beams may include a firstbeam and a second beam. In some implementations, a number of themultiple beams is equal to a number of slot positions of the multipleslot positions—e.g., there is a one-to-one correspondence between themultiple beams and the number of slot positions.

At block 903, the UE transmits, for the PUCCH resource: a first PUCCHrepetition of multiple PUCCH repetitions using the first beam for afirst slot position of multiple slot positions; and a second PUCCHrepetition of the multiple PUCCH repetitions using the second beam for asecond slot position of the multiple slot positions. The first slotposition and the second slot position may be different slot positions.To illustrate, the UE may transmit the first PUCCH repetition and thesecond PUCCH repetition via wireless radios 2001 a-r and antennas 252a-r. The first repetition and the second repetition may include orcorrespond to first repetition 362 and second repetition 363,respectively. In some implementations, the PUCCH resource may beselected by resource selector logic 2005. Additionally, oralternatively, the first beam and the second beam may be generated usingbeam generator logic 2006. In some implementations, the first beamcorresponds to a first index of the set of indices, the second beamcorresponds to a second index of the set of indices, or both. In someimplementations, the multiple slot positions include multiple slots ormultiple sub-slots of a slot.

In some implementations, a block may include, after transmitting thePUCCH resource, the UE receiving a third RRC configuration including asecond PUCCH resource and a fourth RRC configuration including a secondPUCCH format; and determining whether a set of one or more beams of thesecond PUCCH resource includes a single beam. If the set of one or morebeams includes a single beam, the UE may perform PUCCH repetition usingthe single beam, such as PUCCH repetition across multiple slot positionswhere each PUCCH repetition is transmitted using the same beam (e.g.,the same beam pattern). In some implementations, when a number of themultiple beams is less than a number of slot positions of the multipleslot positions, performing PUCCH repetition includes: cycling throughthe multiple beams for a first set of slot positions of the multipleslot positions, the first set of slot positions including a number ofslot positions equal to the number of the multiple beams; and using oneor more beams of the multiple beams for a second set of slot positionsof the multiple slot positions.

Referring to FIG. 10, at block 1000, the UE receives Downlink ControlInformation (DCI) including a PRI field codepoint. To illustrate, the UEmay receive the DCI via wireless radios 2001 a-r and antennas 252 a-r.The DCI may include or correspond to first message 361.

At block 1001, the UE determines, based on the PRI field codepoint,whether to transmit a PUCCH repetition within a slot position using asingle PUCCH resource or transmit multiple PUCCH repetitions within theslot position using multiple PUCCH resources responsive to determiningto transmit the multiple PUCCH repetitions within the slot positionusing the multiple PUCCH resources. For example, the UE may determine,based on the PRI field codepoint, to transmit PUCCH repetition within aslot position using a single PUCCH resource, such that repetition doesnot occur within the slot position, but may occur across multiple slotpositions. As another example, the UE may determine, based on the PRIfield codepoint, to transmit PUCCH repetition within a slot positionusing multiple PUCCH repetitions within the slot position using themultiple PUCCH resources, such that repetition occurs within the slotposition, as described further herein. The slot position may include aslot or a sub-slot of the slot. In some implementations, the slotposition is a sub-slot of a slot.

At block 1002, the UE transmits multiple PUCCH repetitions within theslot position using the multiple PUCCH resources. In someimplementations, transmitting the multiple PUCCH repetitions includes:transmitting, using a first PUCCH resource of the multiple PUCCHresources, a first PUCCH repetition of the multiple PUCCH repetitionswithin the slot position; and transmitting, by the UE using a secondPUCCH resource of the multiple PUCCH resources, a second PUCCHrepetition of the multiple PUCCH repetitions within the slot position.To illustrate, the UE may transmit a first PUCCH repetition and a secondPUCCH repetition via wireless radios 2001 a-r and antennas 252 a-r. Thefirst PUCCH repetition and the second PUCCH repetition may include orcorrespond to first repetition 362 and second repetition 363,respectively.

Alternatively, prior to mapping, theUE may receive a MAC-CE, and may activate, based on the MAC-CE, amapping functionality at the UE for mapping the PRI field codepoint tothe set of one or more interpreted PRI values.

In some implementations, the set of one or more interpreted PRI valuesincludes a single interpreted PRI value. In some implementations, thePRI field codepoint may be mapped to a single interpreted value. Forexample, the interpreted PRI value may be mapped to the same value or adifferent value as a value of the PRI field codepoint. Alternatively,the set of one or more interpreted PRI values may include multipleinterpreted PRI values. In some such implementations, at least one ofthe multiple interpreted PRI values has the same value as a value of thePRI field codepoint. When the PRI field codepoint maps to multipleinterpreted PRI values, the multiple interpreted PRI values may includea first interpreted PRI value corresponding to a first PUCCH resourceand a second interpreted PRI value corresponding to a second PUCCHresource. The first PUCCH resource may correspond to a first activatedbeam, and the second PUCCH resource may correspond to a second activatedbeam different from the first activated beam.

In some implementations, the DCI may include a Downlink (DL) DCIscheduling a Physical Downlink Shared Channel (PDSCH), and the PUCCHrepetition includes a Hybrid Automatic Repeat Request (HARQ)-ACKcodebook. Additionally, or alternatively, a block may be included inwhich the UE receives multiple DCIs, such as multiple DCIs that includethe DCI. Each of the multiple DCIs may include including a correspondingPRI codepoint and a corresponding Hybrid Automatic Repeat Request (HARQ)feedback timing indicator field. In some implementations, thecorresponding vales of the HARQ feedback timing indicator field of themultiple DCIs indicate the same slot position for PUCCH transmission ofHARQ-ACK feedback. The UE may identify a last detected DCI of the set ofDCIs and may determine to perform PUCCH repetition if the correspondingPRI field codepoint of the last detected DCI indicates or corresponds tomultiple PRI values. In some implementations, the UE may determine toperform PUCCH repetition based on at least one DCI of the set of DCI hasa corresponding PRI field codepoint that indicates or corresponds tomultiple PRI values. To illustrate, the UE may identify a last detectedDCI of the set of DCIs and, when the detected DCI corresponds to asingle PRI value and when the at least one DCI of the set of DCI has acorresponding PRI field codepoint that indicates multiple PRI values,may use a first PUCCH resource corresponding to the single PRI value andmay use a second PUCCH resource corresponding to a most recentlyreceived DCI of the at least one received DCI that includes the value ofthe PRI field codepoint corresponding to the multiple PRI values.

Referring to FIG. 11, at block 1100, the UE receives DCI including a PRIfield codepoint. To illustrate, the UE may receive the DCI via wirelessradios 2001 a-r and antennas 252 a-r. The DCI may include or correspondto first message 361.

At block 1101, the UE maps the PRI field codepoint to a set of one ormore interpreted PRI values. For example, the UE may map the PRI fieldcode to the set of one or more interpreted PRI values using mappinginformation 2003.

At block 1102, the UE transmits multiple PUCCH repetitions within a slotposition using multiple PUCCH resources based on the set of one or moreinterpreted PRI values. In some implementations, transmitting themultiple PUCCH repetitions includes: transmitting, using a first PUCCHresource of the multiple PUCCH resources, a first PUCCH repetition ofthe multiple PUCCH repetitions within the slot position; andtransmitting, using a second PUCCH resource of the multiple PUCCHresources, a second PUCCH repetition of the multiple PUCCH repetitionswithin the slot position. To illustrate, the UE may transmit a firstPUCCH repetition and a second PUCCH repetition via wireless radios 2001a-r and antennas 252 a-r. The first PUCCH repetition and the secondPUCCH repetition may include or correspond to first repetition 362 andsecond repetition 363, respectively. In some implementations, the PUCCHresource may be selected by resource selector logic 2005. Additionally,or alternatively, the first beam and the second beam may be generatedusing beam generator logic 2006. The slot position may include a slot ora sub-slot of the slot. In some implementations, the slot position is asub-slot of a slot.

In some implementations, the UE identifies the PRI field codepoint basedon the DCI. To illustrate, the UE may identify the PRI field codepointusing setting identifier logic 2004.

In some implementations, a block may include the UE determining whetherthe DCI points to multiple TCI states. The UE may determine to notperform mapping based on a determination that the DCI points to a singleTCI state. Alternatively, the UE may determine to perform mapping basedon a determination that the DCI points to the multiple TCI states. Basedon a determination to perform the PUCCH repetition using the multiplePUCCH resources, the UE may select a first PUCCH resource as a first ofthe multiple PUCCH resources, the first PUCCH resource corresponding tothe value of the PRI filed codepoint, and select a second PUCCH resourceas a second of the multiple PUCCH resources. To illustrate, the UE mayselect the first and second PUCCH resources using the resource selectorlogic 2005. The second PUCCH resource is selected from a set ofavailable PUCCH resources within a PUCCH resource set, excluding theselected PUCCH resource. For example, the second resource may beselected based on satisfying one or more rules/conditions, such as notoverlapping with the first PUCCH resource, starting after the firstPUCCH resource, having a different activated beam from an activated beamof the first PUCCH resource, having an activated beam corresponding tothe same QCL source as at least one TCI state pointed to by the DCI, ora combination thereof.
